I was hoping it wouldn't hit my repos, but the trickle is turning into a wave of AI-generated PRs that... all they do is suck up what little time I have available for PR review trying to see if there's anything of value in the AI-generated code. There usually isn't.

These little USB-C adapters are neat! I can get most typical project voltages through Werewolf's VFLEX power adapters, and use them as a substitute for my bench power supply—in some cases.
(Note: Werewolf sent me a couple sets to test.)

I'm surprised I don't see more people hacking on the RP1's functionality on the Pi 5 / CM5 / Pi 500 — here's a device tree overlay enabling full PPS pin support through RP1, including PPS echo to measure Linux kernel latency for things like timing signals: github.com/josh-blake/p...

Just ordered 16 GB of RAM for $44
Feels like I won the lottery.
Only catch? It's DDR2 ECC.

Finally re-routed coax from our attic antenna to the basement rack for HDHomeRun to be there instead of the living room.
My 5 yo daughter proudly crimped her first coax F connector (with a little help ofc). She also popped on hearing protection and vacuumed up the floor lol.
